Problem description

Integer overflow in pcre_compile.c in Perl Compatible Regular
Expressions (PCRE) before 6.2, as used in multiple products, allows
attackers to execute arbitrary code via quantifier values in regular
expressions, which leads to a heap-based buffer overflow.
The python packages use a private copy of pcre code.
The updated packages have been patched to correct this problem.
